Abstract: 625,776. Supplying fuel to liquid-fuel burners. LUCAS, Ltd., J., and IFIELD, R. J. March 31, 1947, No. 8607. [Class 75(i)] [Also in Group XXVI] Means for controlling the supply of liquid fuel to two groups of burner nozzles 15, 19, Fig. 1, disposed e.g. in the combustion chamber or chambers of a furnace, or jetpropulsion or other prime mover, comprises a hollow body 1 divided into compartments 3, 4 by a transverse partition 2 having a seating for a spring loaded valve 5, electromagnetic means for moving the valve 5 on and off its seating, and a fuel supply pipe 18 connected with the compartment 3, the nozzles 15 being connected to the chamber 4, and the nozzles 19 being connected either to the compartment 3 or to the supply pipe 18. The electromagnetic means may comprise a solenoid 9 having a core 10 either engaging the valve 5 directly or being connected thereto by a stem 11. When the solenoid 9 is energised the core 10 is retracted from the valve 5 which is closed by its spring 6 and fuel flows only to the nozzles 19 unless the fuel pressure is sufficient to open the valve 5. On de-energising the solenoid 9 a spring 13 forces the core 10 to push open the valve 5 so that fuel flows to both sets of nozzles 15, 19. An alternative construction is described in which the valve has a stem slidably associated with and connected by a tension spring to the movable solenoid core which may be controlled by switch means responsive to time or to the motion or speed of a part of a prime mover supplied with fuel by the burner nozzles.

Title: Improvements in and relating to fluid pressure motors
Inventor: LANSKY ZDENEK JOHN
IPC: F15B15/22
Filed: 1962-03-09
Abstract: 1,003,400. Fluid pressure apparatus. PARKER-HANNIFIN CORPORATION. March 9, 1962, No. 9183/62. Heading F1P. [Also in Division F2] A fluid pressure motor comprises a piston 20 reciprocable in a cylinder 20, co-operating means on the piston and cylinder forming a cushioning chamber 91 when the piston nears the end of a stroke in the cylinder, a port 34 in the cylinder for admitting pressure fluid thereto, an unrestricted passage along the internal periphery of the cylinder connecting the port with the cushioning chamber, and check valve means 54 in the unrestricted passage for permitting fluid flow from the port to the chamber and preventing flow from the chamber to the port. The piston 20 divides the cylinder 10 into first and second chambers 91, 90, and the motor has first and second heads 12, 11 for closing the chambers, the first port 34 being in the first head for admitting and exhausting fluid to and from the first chamber, and a second port 66 in the first head isolated from the first port and connected by a passage 87 to a third port 78 in the second head for admitting and exhausting fluid to and from the second chamber. The passage consists of a tube 87 which is received with end play in recesses 85, 86 in the heads, seals 88 preventing leakage between the tube and heads. The movement of the piston 20 is cushioned at the end of its strokes by restricting the flow of fluid being exhausted from whichever chamber is diminishing in volume and the check valve 54 permits unrestricted flow to the chamber when the stroke of the piston is reversed. The piston consists of a resilient annulus 22 mounted on a plate 21 secured between plungers 28, 29 on a reduced portion 26 of a rod 15. The plungers are adapted to co-operate with sleeves 44, 73 towards the end of the strokes of the piston to prevent flow from whichever chamber is diminishing in volume. The sleeves are mounted so as to move radially on seals 47 in adaptors 40, 71 secured to the heads to accommodate any misalignment between the plungers and sleeves. When the piston is moving to the right and the plunger has engaged the sleeve 44, fluid can only flow from the chamber 91 through passages 61, 58 to the port 34 at a rate determined by an adjustable throttle valve 62 to cushion the movement of the piston. Upon reversal of the direction of fluid supplied to the motor, fluid flows from the port 34 and through slots 75 in the adaptor 40 to an annular space 65. Fluid flows from the space 65 to the chamber 91 past the check valve 54 which is in the form of a packing ring having inner and outer lips. The packing prevents flow from the chamber 91 to the space 65 but permits unrestricted flow in the opposite direction so that the piston can be moved rapidly from its extreme position. The adaptor 71 at the other end of the cylinder operates in an identical fashion to the adaptor 40.

Title: Improvements in or relating to conveyors for feeding workpieces to metal cutting andlike machine tools
IPC: B23Q7/00
Filed: 1953-04-09
Abstract: 729,687. Endless conveyers. SOC. DES USINES A TUBES DE LA SARRE. April 9, 1953 [April 9, 1952], No. 9700/53. Class 78 (1). [Also in Group XXII] A conveyer arrangement for feeding workpieces to metal cutting and like machine tools wherein at least one conveyer that includes at least one endless chain, belt, or the like is employed, has the conveyer provided with a plurality of pairs of rollers, the rollers of each pair being side by side with their axes parallel to the axis along which the conveyer is adapted to advance the workpieces carried thereon, the arrangement being such that whilst in operation each workpiece to be machined rests on at least one pair of rollers and is located against sideways movement by this pair of rollers. In an arrangement for screw-threading both ends of a number of tubes, two conveyers 1, 2, Fig. 2, are provided. Each conveyer consists of an endless chain carried by a driving sprocket 3, 5, at one end and a guide sprocket 4, 6 at the other. The drive sprockets are rotated by gearing 37, Fig. 3, from a motor 36. The chain links 8 have depressions 9 so that the tubes a may engage supporting rollers 22, 23, arranged at intervals along the conveyer. The rollers have their axes parallel to the direction of movement of the conveyers and centralize the workpieces with respect to the axial plane of tool-heads F, G. Height adjustment to bring the work into line with the tool-spindles is effected by simultaneously moving a series of wedges 16 by a screwed spindle. The wedges bear on the undersides of vertical members 14 which slide in the uprights 10 of the frame and which have angle pieces 12, 13 to support the upper and lower runs of the conveyer respectively. The tubes are pushed along the transverse rails 39 to bring them into operating position and discharged on to rails 35, 40 by triangular members 26 pivoted at 28, Fig. 4, which are tilted by hydraulic or pneumatic cylinders operating through linkage 31-34. A tube, after being pushed on to the conveyer 1, Fig. 2, is moved by the conveyer up to the tool-head F for screw-threading one end, it is then retracted by reversing the conveyer belt, then moved by the plates 26 to the rails 35 where it may be transferred to the conveyer 2. This conveyer feeds the tube in the opposite direction to the tool-head G where the opposite end is threaded, the tube finally being moved off at a<SP>5</SP> on to the rails 40.

Abstract: 1,029,495. Wrapping-machines. FRANKLIN ELECTRIC CO. Inc. March 6, 1964, No. 9710/64. Heading B8C. [Also in Divisions B4 and B6] Articles, e.g. trays, carrying food, are supplied on a plate 26 by a pusher conveyer 23. to a lift 66 on which they are raised to a position where they are transferred by a rack 82, together with the end portion of a wrapper film 166, Figs. 2-3 (not shown), on to a second lift 67 which is raised to the level of a plate 123 at which the wrapper is tack-sealed before being cut from the web (see Division B4). Final sealing is effected before the article is removed on a conveyer belt 56. The lifts 66, 67 are pivotally supported by two pairs of pivoted bars 68, 69 and are cam-operated. A switch 73c operates to stop the main drive if an article jams the lifts. As an article is pushed on to the lift 67 by the rack 82, it engages a floating member 100 slidable in the grooved surface of the lift 67. The rack 82 is retracted and the lifts 66, 67 vertically displaced. Fig. 5 (not shown). The film 166 engages the underside of a dancer bar 147, thereby folding itself round the top and one side of the article as the lift 67 rises. A second rack 98 has a foot 100a which engages the member 100 to eject the partially wrapped article on to the plate 123. A heater 124 tack-seals the film under the article before a reciprocable knife 109 is camoperated against a fixed blade 111 to cut the film. A pair of arms 122 carried on chains 117 move the package past ploughs 128 which fold its ends. As the package passes between heaters 127 which seal its ends and over a heater 126, a shoe 140 is cam-operated to press the package downwards. If the ends of the film are long enough to be turned under the package, the heater 126 both seals them and secures them to the underside of the package. The arms 122 then move the completed package on to the discharge conveyer 56. An adjusting mechanism 256 enables guide rails 255 to accommodate articles of varying length. A stop 257 switches off the machine if an article is too high. As an article is pushed against the web of film 166 and on to the lift 67, the pull on the web pivots an arm 226, thereby causing a roller 175 to feed the web forward (see Division B6).
